What is Joule?
The joule (symbol: J) is the base unit of energy in the International System of Units (SI).
It is equal to the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of the force’s motion through a distance of one meter.
Common Uses
The joule is used in all fields of science and engineering to measure work, energy, and heat. It is a key unit in physics for calculating kinetic energy, potential energy, and thermal energy.
What is Kilowatt-hour?
The kilowatt-hour (symbol: kWh) is a composite unit of energy equal to one kilowatt (kW) of power sustained for one hour.
One kilowatt-hour is equal to 3.6 million joules (3.6 MJ).
Common Uses
The kilowatt-hour is the standard unit used by electric utilities for billing consumers. It measures the amount of electrical energy consumed by households and businesses over time.
How many kilowatt-hour are in a joule?
There are 2.7778e-7 kilowatt-hour in 1 joule.
